text: This technique has been applied to a wide range of problems since it first was published in 1993.
  Applications: 
  * representing vector fields by approximation a field lines of the input vector field
  ** flow-visualization method for steady ( time independent) flows. Here field lines are called streamlines
  ** Visual exploration of 2D autonomous dynamical systems
  ** windy maps
  ** water directions
  * artistic effects to generate fancy images
  ** pencil drawing
  *** automatic pencil drawing generation technique using LIC pencil filter
  ** Automatic generation of hair texture
  ** creating marbling texture
  * Terrain generalization: creating generalized shaded relief
